The AMN - Artificial Mains Network, also known as LISN - Line Impedance Stabilization
Network - is the ancilliary device intended for repeatable and accurate measurement of
the disturbance voltage that an EUT (Equipment Under Test) may inject into the power
line or mains.
This is obtained by providing well known impedance value and phase response across
the frequency range of the test.
L3-500 is suitable for measurement on AC 3-phase power circuits from DC to 60 Hz.
The equivalent V-Network circuit of 50 Ω // (5 Ω + 50 μH) with 250μH choke is fully
compliant with the reference standards.
PMM Artificial Mains Networks provide robust and stable mechanical construction, high
quality electric components, easy and perfect grounding, solid input-output power connections. They can be used in conjunction with any EMI receiver or spectrum analyzer and
offer features required for safe, repeatable and accurate measurements.
